I'm not a hardware guy or sys admin person so forgive me if this is a stupid
question. Leaving out all other variables(such as IO), should I expect
performance to be the same in a databse if the server it is riding at is at 90%
cpu usages as opposed to 10%? since there would still be spare cycles? Or is
there a declining returns as you get closing to the maximum available cpu
usage?
